To all whom, 712$ 'nmy concern:

Be it known that I, W'nalmii l Monsic, a

citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Ini iroveiiients in Garbaged ui'naces, ol' whicht e following'is a specification.

My invention relates" to furnaces designed for the buri'iing of garbage; and its novelty consists in the construction and ad ptation of the parts, as will be more fully hereinafter pointed out.

in the drawings, Figure l is a longitudinal 5 vertical section of a furnace embodying my invention, and Fig. 2 is a vertical transverse section of the same on the plane of the line 2 .2 5

in Fig. 1.

In the drawings, 1 is the primary combusl tion-chamber or oven, provided with end walls 2 and 20, side walls 3 and 30, and a roof 4, which has a door 5, tlirfiugh which the garbage is fed. It also has a primary grate 6 and a.sloping receiving-phitforni 7, provided with suitable vertically-placed openings or perforations 8.

Arranged at the bottom of the furnace is the gas-expanding chamber 9, the bottom of 1 which is the floor it] of the furnace and inter mediate which and the platform 7 is placed a sloping curtain or platform ll, so that between this curtain and the platform there is 1 formed a due 12.

Between the grate 6 and the platform 7 and reaching down to the floor 10 is a partition l3, separating the lire-box or ash-pit H from the interior of the furnace. The curtain i l, while it is secured to and supported from the end wall 20, does not extend quite to the {)ttllilthiltEl-i, there being a chamber 15 formed between the lower terminus ll! of the partition, the floor It), and theplatform 7.

Adjacent to the wall .20 is arranged the chimney l6, enlarged somewhat at the bottom, where it is provided with a grate l7 and a plurality of transverse arched partitions 18 18 of lire-brick above the same. These "partitions are perforated, as at 180 lSO, to permit of the free passage of the gases, as hereinafter described. The chimney is [)lOVltlWl 1 with adoor l 9 to admit ofaccess to thcgi'at e l 7.

Beneath the floor it) there are arranged a plurality of air-conduits to L0. 'lhese extend from the outer air, where they are provided with V511VG COIltIOlhWi inlets along the bottom of the furnace and thence up through the wall 13 or in any other convenient man- I ner, so that they may discharge their heated contents bencat h the grate 6. t Suitable openings, as 21, extend from the expanding-cliamhert) to the space above the grate l7.

It will of course be understood without any further explanation that the usual adjuncts of dampers, stoke-holes, and the like are provided and that the parts are made of suitable materials, such as steel or lire-brick, in the manner customary with engineers and other persons skilled in the art.

The mode of operating the apparatus is as f follows: A fire is first built upon the grate 17, any ordinary fuel being employed. This is for the purpose of establishing a. current of air through the apparatus and heating the iartitions lo l8. A lire is then lighted upon the grate t}. This heats the air in the primary combustion-chanibcr and heais the inclined platform 7. After these two tires iand the garbage to be treated is thrown. down upon the platform 7. it is there 'lirst j dried and then burned. if the quantity is great, the garbage is continually stoked down- I ward toward the grate 6, and a portion of it 1 serves as additional fuel to ass t in the operations of the apparatus. Portions of the garbage also fall down through the apertures Jr 8 into the flue 12 add chamber l5, where t they are speedily destroyed. The products l and partie .1 products of combustion pass upward along the sloping platform 7, the direction of their movement being assisted by its position. They then pass around its uppermost end and downward through the flue l2, fori'ned between it and the curtain ll, into the-chamber 15. They then pass into the expanding-cliainber 9. Here they expand and the reactions which have been taking place down to this time cease or almost cease. They then pass out at the upper end of the chamber ti into the chimney above the grate 17. The fresh fire on this grate auses the I innnmliate ignition olall otthe gases capable of such a reaction and they pass upward i through the holes 1st) 180 in the partitions 18 l8 and leave the throat of the chimney practically consumed and innocuous.

l The inclination of the platform 7 upward t away from the grate constantly decreases the area of the coinbustion-chainber, and thereby causes a-niore intimate contact of the products of coinljiustion with the garbage on the platform, such inclination also facilitating What I claim as new is the downward. movement of portions of the superposed garbage to the grate to form ditional fuel thereon.

The downward incline oi the curtain 11 greatly facilitates the passage with the prod.- ucts of combustion of the very light, dried, and burned particles deposited on the apron both though the apertures of the platform and around the upper end thereof. The position of the apron and platform also forms an inclined flue, through which the products of combustion pass downward, and owing to their superior lightness the lightly-heated gases are caused by such" inclination of the line to more closely contact with the under side of the platform, keeping it hot and greatly facilitating the initial incineration of the garbage on the pla tfornr.

Theplatforin 7, the curtain 11, and the partitions 18 18, together with the walls of the furnace, soon become very hot and by their radiation assist inn terially in maintaining the continuity of the operation of the apparatus.

In order further to utilize the heat,-I place --the air-conduits 4.0 40 beneath the furnacefloor. As soon as theiurnace is fairly under way the air is let into the inlet-valve, be-

comes heated'in its passage under the floor 10, and finally emerges beneath the grate sufiiciently heated materially to increase the economy of the operation of the furnace.
